Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical formulation parameters. Quality is verified through a suite of analytical tests including determination of hydroxyl value (OHV), isocyanate content (NCO%) where applicable, viscosity, and moisture content. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. This product is moisture-sensitive; ensure containers are sealed tightly after use to prevent absorption of atmospheric moisture which may affect performance.
